Process And Mismatch Insensitive Temperature Sensor
A temperature sensor that is insensitive to process variation and mismatch is disclosed. The temperature sensor includes a PTAT voltage generator, a sampling and gain boosting circuit, a filter and a controller. The PTAT voltage generator utilizes a plurality of current sources, each of which is in electrical communication with the same diode, or diode stack. The output of the PTAT voltage generator is sampled and amplified with the sampling and gain boosting circuit. The output of the sampling and gain boosting circuit is then filtered using a low pass filter. The selection of the current mirrors, the sampling timing and other signals are provided by the controller. In some simulations, the output from the temperature sensor was accurate to within 1.5° C., using a one temperature calibration process.

Thermocouple pre-aging and temperature drift compensation
A temperature drift compensation method includes pre-aging a thermocouple, during which the thermocouple is subjected to temperatures and/or pressures that cause or facilitate an oxidation growth on the conductor elements of the thermocouple. During the pre-aging, temperature readings of the thermocouple are recorded, and a model including a time-based exponential expression is derived from the temperature readings. In addition, a temperature sensor system includes a pre-aged thermocouple, and a temperature compensation circuit that modifies initial temperature readings from the pre-aged thermocouple according to a model including a time-based exponential expression.
